Application filed September To all whom it may concern:

Be it known that T, FERDINAND A. Rarrnn, a citizen of the United States, residing Cleveland, in the county of Cuyahoga and State of @hio, have invented certain new vdrocarbonand useful Improvements in U Lamps, of which the following is a specification.

This invention relates to vapor lamps and more especially to that type of lamp which hydro-carbon is used in connection with the incandescent mantle.

It has for its principal object the provision of a lamp which will produce illumination of the highest efiiciency; the provision of means which-will prevent the break: of the shades used in connection therewith and also to provide an efficient construction whereby the removal of parts to be cleaned may be simplified. and also to provide a construction whereby certain parts may be disassembled for convenience in packing.

Further objects of the invention are the provision of means whereby the vaporizing structure maybe conveniently pro-heated when it is desired to put the lamp in operation these means being so constructed as to serve to hold the associated parts in their proper position; the provision of means which will allow different size shades to be used in connection therewith and the provision of a lamp or this character which will be simple in operation, cheap of manufacture and etficient in operation.

The foregoing objects are obtained in the embodiment of the invention shown in the accompanying drawings, wherein like reference numerals designate similar parts of reference throughout the various views and wherein Figure 1 is a side elevation of the upper part of the lamp the shade being shown in section and the fluid reservoir being omitted; Fig. 2 is a central vertical section through the operating parts; and Figs. 3 and i are sectional details on the lines 8 and iof Fig. 2.

The device comprises a reservoir, not shown, which serves as a base or standard for the lamp and to which is secured a supply pipe 1 provided with a needle valve 2 whereby the flow of fluid may be controlled. The upper end of the needle valve casino is provided with a reduced threaded portion 3 which has applied to it a cup shaped nut Specification of Letters Pilbfillt Patented Apr. 29, 1920.

i and this nut may be knurled about its 1 1 a v2 eriphery ioi convenience in applying and d with an annular recess 5 into placed an absoroent packing for ose to be hereinafter described.

i i 1s provided with an internally threaded bore 8 into which is threaded a nipple 7 end of a 3 provided 'tl very fine bore 9 whereby 1 fluid is allowed to communicate with the interior of the tube 8, the tube 8 is packed with quantity of asthereby to break up the fluid into 7 particl s and to equalize the pressure A o the mantles. The tube 8 is pro 1 'ded at its upper end with a cap 11 which i a threaded thereon and which is adapted to he slipped into a bore in the bottom of a cylindrical casting 12. The o 11 is provided at its top with a reduced re 13 to allow the gas to pass upwardly through pipe 1 1- where it is conducted thr rg'h a manifold 15 and thence clownwardly to the mantles 16 through the pipes 17 and 18, the mantles being suspended upon the bottom of the pipes by the customary hangers 19. The cylindrical cast-i 12 is provided with a head 20 at one end and at the other end has threaded therei cu ved tube 21 whose end lies near to the interior of the shade 22, thus the cast- 12 serves as a mixing chamber whereby the iet of is mixed with fresh air taken remote end of the tube 21.

in from the The foregoing; is customary in this type of lamp and wil require no further explanation.

The shade supporting structure comprises a horizontal plate 23 which is secured at its central portion between a shoulder 27 formed upon the upper end of the needle valve casing and the nut land has secured to its ends vertical rods or standards 25 which extend above the operating parts of the lamp and support a similar shaped plate 26, which is rigidly secured by being clamped between the upper portion of the manifold 15 and the shoulder 27 formed upon the bottom of a rod 28 as shown particularly in 2 the rod 28 forming a convenient support for the arms of the shade supporting structure, this structure comprises a disk 29 which. is vertically adjustable upon the rod 28 and is secured in a they are bent back upon themselves as at 3st and upwardly asat 35. By this particular construction I provide a means whereby the shade may he supported on the portions and dueto the fact that the wire or rod of which they are composed presents but a very slight contact between itself and the shade I allow the heat generated by the lamp to reach all parts of the shade equally, providing thereby against unequal expansion and contraction of the shade. 1'. also allow for shades provided with varying size openings at their tops to be applied to the supporting arms due to the resiliency of said arms.

It will be readily seen thatshades of different depths maybe supportedupon this structure by adjusting the disk 29 with its associated parts vertically upon the post 28 as shown in'dotted lines in Fig. l and the top of the post 28 may have applied to it an ornamental structure 36 if desired. The particular point of this construction pertains to the pre-heating arrangement for the vaporizing tube 8, and the fact that this arrangement is utilized for locking the parts in an assembled condition upon receipt thereof from the shipper.

By first saturating the absorbent material in the cup 5 with a volatile fluid and igniting the same, the flames and heat thereof are caused to thoroughly heat the vaporizing tube thus generating suiiicient gas to ignite the mantles whereupon the heat generated by the mantles is sufficient to keep the vaporizing tube heated during the burning of the lamp.

I claim:

1. In a lamp, the combination of a supply pipe and valve, an upright vaporizing tube communicating therewith and supported thereby, a starting cup screwed on the upper end of the valve casing, below the tube, and a shade-supporting structure supported by the pipe and casing and including a cross plate clamped to said casing by said cup.

2. in a lamp, the combination of an oil supply valve casing having a nipple at its upper end threaded internally and externally, a shade support including a cross plate fitting on said nipple, a starting cup screwed on the nipple and clamping said plate to the casing, and a vaporizing tube screwed into the nipple and projecting above the cup.

In a lamp, the combination of a valved supply pipe, an upright vaporizing tube communicating therewith, a mixing tube having a slip connection with the upper end of the vaporizing tube, a manifold connected to the upper end of the vaporizing tube, and a supporting structure for the mixing tube and manifold, including a lower cross plate mounted on the supply pipe, an upper cross plate fastened to the manifold, and rods connecting the plates.

4. In a lamp, the combination with a manifold and mantle tubes depending therefrom, a support for said manifold, a rod projecting upwardly from said support, and a shade holder adjustably mounted on said rod.

In testimony whereof, I do affix my signature in presence of two witnesses.
